Vaccination protects not just the individual, but the entire community.
Cada invierno, Chile enfrenta una tensión conocida entre el frío que reúne a las personas y los virus que prosperan en esa cercanía. En 2026, esa tensión se ha vuelto estadística: el 32,2% de las consultas de urgencia corresponden a enfermedades respiratorias, lideradas por rinovirus e influenza A, con una inusual alza de influenza B. Los expertos recuerdan que la vacunación no es solo un acto individual, sino un gesto de solidaridad comunitaria, y que las herramientas más antiguas —el lavado de manos, la ventilación, la consulta oportuna— siguen siendo las más confiables frente a la ola invernal.
- Las consultas de urgencia por causas respiratorias alcanzaron el 32,2%, el nivel más alto del año, con el rinovirus y la influenza A como principales responsables.
- La influenza B registró un salto inesperado del 7,2% al 10,2% en una sola semana, una señal de alerta que rompe el patrón estacional habitual.
- Hospitales y centros de atención primaria acumulan presión creciente: las salas de espera llenas no solo retrasan la atención, sino que se convierten en nuevos focos de contagio.
- Expertos insisten en que la vacunación, la higiene y la ventilación de espacios cerrados son las defensas más efectivas, especialmente para adultos mayores, embarazadas y personas con enfermedades crónicas.
- Las herramientas de salud digital —consultas remotas, seguimiento de síntomas, agendamiento en línea— emergen como válvula de alivio para el sistema, aunque no reemplazan la prevención.
El invierno 2026 llegó a Chile con una carga conocida: las salas de urgencia se llenan, los virus circulan y el sistema de salud comienza a sentir el peso de la temporada. Según el último reporte semanal de la Campaña de Invierno del Ministerio de Salud, las enfermedades respiratorias ya representan el 32,2% de todas las consultas de urgencia, la cifra más alta registrada en lo que va del año. El rinovirus lidera con el 35,8% de los casos detectados, seguido por la influenza A con un 26,8%. Pero la señal más inquietante es el alza de influenza B, que saltó del 7,2% al 10,2% en una semana, un comportamiento inusual para esta etapa de la temporada.
Jaime Lepe, director de la Escuela de Medicina de la Universidad del Alba, explica el mecanismo detrás del fenómeno: el frío concentra a las personas en espacios cerrados y mal ventilados, condiciones ideales para la transmisión viral. Advierte que, sin medidas preventivas adecuadas, el aumento de consultas podría derivar en mayores hospitalizaciones. La vacunación, subraya, sigue siendo la herramienta más eficaz, no solo porque protege a quien se vacuna, sino porque frena la circulación del virus en toda la comunidad. A eso se suman hábitos simples: lavado de manos, ventilación de ambientes y uso de mascarilla ante síntomas.
La doctora María José Gamboa, referente en salud digital de Minsait Chile, agrega recomendaciones prácticas: cubrirse con el codo al toser o estornudar, consultar al médico si los síntomas persisten y evitar la automedicación. También señala que las tecnologías digitales —consultas remotas, seguimiento de síntomas, acceso a registros clínicos— pueden aliviar la presión sobre los centros de salud al resolver casos menos complejos sin necesidad de visitas presenciales. Minsait ha desarrollado plataformas de este tipo en otros mercados, como la Tarjeta Sanitaria Virtual de Madrid, que permite a millones de usuarios gestionar citas, ver resultados y realizar videoconsultas desde el teléfono.
Sin embargo, los expertos coinciden: la tecnología es un complemento, no un reemplazo. Las próximas semanas pondrán a prueba si la prevención logra adelantarse a la transmisión, especialmente para quienes más lo necesitan: adultos mayores, embarazadas, niños pequeños y personas con enfermedades crónicas.
Winter has arrived in Chile, and with it, a familiar crisis is building in emergency rooms across the country. According to the latest weekly report from the Health Ministry's 2026 Winter Campaign, respiratory illnesses now account for 32.2% of all emergency visits—the highest proportion recorded so far this year. Cold temperatures have driven people indoors, into poorly ventilated spaces, and the viruses have followed.
Rhinovirus is the dominant culprit, responsible for 35.8% of detected cases, though this represents a slight decline from the previous week's 40.8%. Influenza A holds second place at 26.8% of cases, remaining relatively stable week to week. But there's an unexpected guest: Influenza B, now accounting for 10.2% of cases, has surged from just 7.2% the week before—an unusual spike for this time of year, when the virus typically doesn't gain traction until later in the season.
Jaime Lepe, director of the School of Medicine at Universidad del Alba, explains the mechanics of winter's respiratory trap. The cold months concentrate people in enclosed spaces with minimal air circulation, creating ideal conditions for viral transmission. "We're seeing significant circulation of various respiratory viruses," he says, "which could translate into increased consultations and hospitalizations if proper preventive measures aren't adopted." Vaccination remains the most effective tool for preventing severe illness and its complications, he emphasizes. But prevention extends beyond the needle. Hand washing, ventilation of indoor spaces, and masking when symptomatic all reduce transmission risk. Vaccination carries an additional benefit: it doesn't just protect the individual who receives it. It slows the virus's movement through the entire community—a critical advantage when influenza, COVID-19, and other respiratory pathogens are circulating simultaneously.
Dr. María José Gamboa, a digital health leader at Minsait Chile, points to other simple but effective habits. When coughing or sneezing, cover the inside of your elbow, not your hand, to avoid contaminating surfaces and dispersing viral particles. Seek medical attention early if symptoms persist, and resist the urge to self-medicate. These small acts compound across a population.
The surge in respiratory consultations creates cascading strain. Hospitals, emergency clinics, and primary care centers face mounting pressure. Patients wait longer for care, and while waiting, they're exposed to additional viruses circulating through crowded waiting areas. Digital health tools offer one potential relief valve. Remote patient guidance, appointment scheduling, symptom tracking, and access to clinical records can resolve less complex cases without requiring in-person visits. Gamboa notes that such technologies allow early risk identification, optimize resources, and reduce unnecessary trips to health facilities during periods of peak demand.
Minsait has developed a SuperApp called MyHealth that consolidates digital health services into a single platform, enabling users to access clinical information, schedule appointments, and monitor their health continuously. While primarily deployed in other markets, it demonstrates the potential of such tools to bring healthcare closer to people and ease the burden on physical facilities. Madrid's Virtual Health Card, also built on Minsait technology, serves millions of users, allowing them to manage appointments, view test results, conduct video consultations, and review medical history from their phones.
Yet experts agree that technology alone cannot carry the load. Keeping vaccinations current, maintaining prevention practices, and seeking timely care when needed remain the most effective defenses against winter's respiratory wave. The vulnerable—elderly people, pregnant women, young children, and those with chronic illnesses—face the greatest risk. For them, and for the healthcare system straining to serve them, the next weeks will test whether prevention can outpace transmission.

La Conversación del Hearth Otra perspectiva de la historia
Why does winter create such a perfect storm for respiratory viruses?
It's partly physics and partly behavior. Cold air drives people indoors, into spaces where air doesn't circulate well. We're packed together, breathing the same air for hours. Viruses love that.
The numbers show rhinovirus leading, but influenza B is doing something unusual. What does that tell us?
That's the unsettling part. Influenza B typically waits until the second half of the year. Seeing it spike now suggests either the virus is shifting its patterns, or conditions this year are unusually favorable for it. Either way, it's a reminder that these patterns aren't fixed.
If vaccination is so effective, why do we still see these surges?
Because vaccination rates aren't universal, and immunity isn't permanent. You need to stay current. But also, vaccination protects you from severe disease—it doesn't guarantee you won't catch the virus. What it does is keep you out of the hospital and alive.
The article mentions digital health tools. Are those actually being used, or is that aspirational?
They exist and work in some places. Madrid's system has millions of users. But they're not a substitute for vaccination or basic hygiene. They're a pressure relief—they keep people with minor symptoms from clogging emergency rooms, freeing up space for those who truly need it.
Who bears the real cost of this surge?
The elderly, pregnant women, young children, people already sick with something else. They're the ones who end up hospitalized. And the healthcare workers who have to manage the overflow.
